HOT-AIR REGISTER.

SPECIFICATION forming part of Letters Patent No. 491,524., datedFebruary 14, 1893.

Application filed September 10, 1892. Serial No. 445,571. (No model.)

To all whom it may concern:

Be it known that 1, FREDERICK BURMEIS- TER, a citizen of the UnitedStates, residing at Cleveland, in the county of Ouyahoga and State ofOhio, have invented a certain new and Improved Hot-Air Register, ofwhich the following is a full, clear,and complete description.

The nature of my invention relates to a register in which the differentparts are cast in such a manner that they are all ready for use whenthey leave the foundry, with the exception of two threaded openings, andone screw which holds all of the parts together.

The object of myimprovement is to provide a practical register which issimple and inexpensive in construction and can be quickly and easily puttogether.

That my invention may be seen and fully understood by others referencewill be had to the following specification and annexed drawings forminga part thereof, in which- Figure 1 is an enlarged top view of theregister; Figs. 2 and 3 are opposite end views; Figs. etand 5 areopposite sectional end views; Fig. 6 is a view of the bar by means ofwhich the leaves are opened and closed; Fig. 7 is a View of thelocking-bar and the segment which reciprocates the bar shown in Fig. 6and Fig. 8 is an end view of one of the leaves.

Similar letters of reference designate like parts in the drawings andspecification.

The frame A, Figs. 1, 2, 3, 4 and 5, hasaboss B in each of the fourcorners. An opening B is cored out of the upper part of the boss B andthrough the four openings thus formed are passed the screws which securethe perforated top or cover to the register. The perforated top iscommon to all hot air registers and it has not been deemed necessary toillustrate or describe the same in connection with this case. Thenotches A, in the top of the frame A, are to receive correspondingprojections on the under side of the perforated cover for the purpose ofholding said cover more firmly in place.

Surrounding the interior of the frameA at the base are the flanges a anda, Figs. 1, 4 and 5. The flange a,on one side of the frameA,is elevatedabove the flange a on the remaining three sides, as shown in Figs. 4 and5, forthe purpose hereinafter described. Cast on the end sections of theflange a are the bearings 19 and b and communicating with the interiorof the bearings 11 are the openings 0, cored out of the frame A, asshown in Fig. 2.

The leaves 0, provided at both ends with the trunnions d which rest inthe bearings 11 and 1), form a bottom to the frame A, when said leavesare closed as illustrated in Fig. 1. The end of each of the leaves Onext to the bearings b'is provided with an upward projecting lug 6,Figs. 1 and S, which has extending therefrom the pin 6, said pin and lugforming an integral part of the leaf O.

The bar D, of essentially the form shown in Fig. 6, is provided at thetop with the pin f, projecting from the face and forming an integralpart thereof, and has at the bottom the dogs or ears f. The holes D, inthe bar D, receive the pins 6' of the lugs cand when the leaves are in avertical position or open to their fullest extent the ears f come incontact with the trunnions d and prevent said leaves from turningcompletely over.

The locking-bar E, Figs. 1 and 7, is provided at the base with the flange E which rests upon the top of the bearings b, when said bar is inplace between the end of the frame A and the bar D. Projecting from thelocking-bar E are the guidesF],whichbearagainstthe barD and assist inretainingsaid barD in place. Screwed or pivoted to the locking-bar E isthe segment F, having a serrated edge and a pin for rotating the same.In the segment F is the slot F into which the pin f of the bar D isreceived. The screw Gpasses through the opening G in the frame A andsecures the locking-bar to the end of said frame. It will now be readilyseen that, by rotating the segment F, the bar D will be reciprocatedbetween the lugs e and the guides E and at the same time open or closethe leaves of the register accord ing to the direction in which saidsegment F is moved. hen the leaves are closed the outside edge of oneouter leaf bears on the underside of the flange a, each successive leafoverlapping the next until the opposite outside edge of the outer leafrests on the flange a. A portion of one of the leaves O is broken awayin Fig. 1 to show a top view of the bearing 1). The trunnions d whichrest in the bearings b extend through the openings 0 and when the bar Dis in place, over the trunn1ons at the opposite end of the leaves 0,said leaves are held securely in place.

WhatI claim as my invention and desire 5 to secure by Letters Patent, is

1. In a hot air register, a series of leaves provided with trunnions atopposite ends, the lugs e and pins e; the frame A having the flange aand the bearings 12 and b, said bear- Io ings b communicating with theopenings c;

and the reciprocating bar D having the piu'f and the downwardlyprojecting ears f, with openlngs to receive the pins 6, in combinationwith the locking-bar E and slotted segment 15 F, said locking-bar beingprovided with a iiange at the'base, theguidesE and secured to the end ofthe frame A, in the manner substantially as and for the purpose setforth;

FREDERICK BURMEISTER.
